In 1874, Georg Cantor published one of the most important papers in math’s 4,000-year history. Some ideas in it were stolen. On this episode of The Quanta Podcast, the first of a two-parter, host Samir Patel speaks with math editor Jordana Cepelewicz about the hard-fought journey to embed the concept of infinity into math’s foundations. The real story is a lot more complicated than the one remembered in math history. These episodes are based on a recent story; stay tuned for the conclusion next week. Explore our new special series, “The Evolving Foundations of Math,” on our website.

Parallel universes, mysterious collapses, divided worlds. These are among the interpretations of quantum theory’s relationship with reality. It’s no wonder that everyone still has questions. But a century after quantum theory emerged, some of its old mysteries may be finally dissolving. On this episode of The Quanta Podcast, host Samir Patel and contributing writer Philip Ball check in on the age-old question: What 𝘪𝘴 reality? This topic was covered in a recent story for Quanta Magazine.

What guides a bat’s internal compass? It’s not the stars in the sky, or the Earth’s magnetic field. On this episode of The Quanta Podcast, host Samir Patel speaks with staff writer Yasemin Saplakoglu about how new research into animals’ sense of direction could help explain the feeling of getting “turned around,” or even why some of us are so bad at finding our way. This topic was covered in a recent story for Quanta Magazine.

In reality, water doesn’t glitch out. It can’t instantly change direction or spurt randomly into the sky. But on a purely mathematical level, such things are possible. On this episode of The Quanta Podcast, host Samir Patel speaks with staff writer Charlie Wood about the equations that describe our rivers, whirlpools, and breezes — and the “unstable blowups” that mathematicians are probing them for. This topic was covered in a recent story for Quanta Magazine.

Every elementary particle falls into one of two categories. Collectivist bosons account for the forces that move us while individualist fermions keep our atoms from collapsing.

In the allegory of Plato’s cave, prisoners see the world only through shadows. Extending this metaphor to AI, AI models are the prisoners and the shadows are streams of data. Are all models converging on a singular representation of reality? On this week’s episode of The Quanta Podcast, host Samir Patel speaks with staff writer Ben Brubaker about how, despite being trained on entirely different data types, different models can somehow develop similar internal representations. This topic was covered in a recent story for Quanta Magazine.

Particle physics hasn't yet found the new physics needed to resolve its deepest mysteries. It’s hard to know what to think about or look for. But the most devoted particle physicists are thinking and looking all the same. On this episode, host Samir Patel and columnist Natalie Wolchover discuss the first of our new series of curiosity-driven essays, Qualia, where Natalie asks particle physicists whether the field is facing a profound crisis.

We already know that what we eat, drink, and inhale can affect which parts of our DNA are expressed, and which aren’t. But recent research poses a shocking idea: A dad’s habits may be encoded in molecules and transmitted to his future kids. On this episode, host Samir Patel and biology editor Hannah Waters dig into the new epigenetic mouse studies exploring whether sperm cells carry more than just genetic information. This topic was covered in a recent story for Quanta Magazine.
